Harry Fleisher, Watertown, Conn., and George H.

Tillett, New York, N. Y., assignors to Roto- Matic Screen Printer, Ltd.,NewYork, N. Y.; a corporation of New York i Application November 7,194i), Serial No,.364,6v01 1 s claims. (omai- 123) This inventionrelates to apparatus for applying designs upon flexible Webs of textilefabrics, paper, and like materials, and more particularly to an improvedapparatus employing a stencil printing screen.

This invention is an improvement over a screen printing apparatusdisclosed in a prior Patent No. 2,210,474, issued August 6, 1940, toGeorge I-I. Tillett, entitled Color printing web.

One object of the present invention is to provide an apparatus of theabove nature having improved counterweight means for the stencilsupporting frame, and improved means to align and adjust said frame.

Another object is to provide an improved form of color squeegee forspreading the color paste upon and through the stencil screen and meansto support the same out of contact with said screen at the rear end ofits stroke.

A further object is to provide improved means to space the coils, orlayers, of printed web from each other when they are Wound upon a spool,

and for permitting the flow of a stream of dry air between the layers ofsaid web after the printing operation.

A still further object is to provide means to secure a web-carryingspool, mounted on a movable carrying truck, in accurate alinement withthe screen printing apparatus, whereby the area of web to be printedwill be in proper transverse registry with the stencil screen.

A still further object oi this invention is to provide an improvedapparatus for applying designs upon fiexible webs of the above nature,which will be relatively inexpensive to manufacture, simple inconstruction, easy to operate by relatively unskilled labor, compact,ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, which will appear as thedescription proceeds, there have been illustrated in the accompanyingdrawings several forms in which the invention may be convenientlyembodied in practice.

Briefly, the screen printing apparatus of this invention includes acentral table for supporting a screen frame, and a pair of spools, onecarrying a roll of web to be printed, and the other serving as a take-uproll for the web after printing. The web to be printed is adhesivelyiiXed to a `carrier belt which is fed manually intermittently from onespool below the screen to be wound upon the other spool. Provision is`also. made of marginal spacer strips secured to the carrier belt sothat when said belt is wound in spiral condition, the color pastevfreshly printed upon the web will be kept out oi contact with theadjacent layer of said Web, whereby smudging of said color will beprevented, and said .fresh color Awill be given alchance to dry. Thespacer stripsalso serve toseparate the successiveilayers of the web andprovide betweenzthiei'n a drying space through which a streamv ofdry'airmaly be forced.

By"lwinding the printedv `web in ,spiral form upon,the takefup spools,`the material 'maybe storedwhile drying or "curing in the minimum ofspace as compared to thefformerrmethods of dryingprinted Webs onelongated nat tables or suspending said webs in `festoons or (loops. Thecompact coiledweb-carrying spools of V the present invention are movablymounted on caster truckss'o as to `facilitate the feeding of the webback again through the printing apparatus for applying additional colorsor printing the web at different areas from those originally printed.

Referring now to the drawings wherein like Vreference numerals designatelike parts through-Y out the several views, the numeral I denotesrasupported by four corner uprights, or legs, Il, I2,

I3, and I4. The front uprights II and I2 are connected Yand braced byhorizontal bars I5, I6, and I1, while the rear uprights I3 and 4 areVlikewise connected and braced by similar horizontalY bars locatedbehind said bars I5, I6, and Il', and concealed thereby as viewed inFigure 1. The front uprights I2 and I3 are connected and braced at thetoplby horizontal side .bars I3, I9, and 2t, and the uprights YIl and isare braced by similar side bars concealed thereby. At each end of theapparatus, provision is made vof upright bars 2| extending from Vthelower horizontal bar Y i5 to the upperrbar il, and a short vertical bar22V extends at each Vside from the intermediate ,horizontal bar I9 tothe lower bar 2G (Figure 2).

' VProvision is also madeof a pairof horizontal Y shafts 23 mounted inandextending between the c brackets 24 (Figures l and 2) which isvertically adjustable in andis secured to the respective upright byabolt 25 passing through an elongated slot rprovided in the bracket Y24and screwthreaded into the respective upright. A hand V,wheel 21 issecured on the front end of each shaft 23 and a sprocket 28 is securedupon the rear end of said shaft. The shafts 23 are extended at theirYfront ends 29Y beyond the uprights Il and I2, and

said-ends are preferably made hexagonal in crosssectionto Vremovablyreceive a manually-operated crank handle 30. i

Thetable top I0 extends rearwardly beyond the corner uprights I'IV andI4, as at 3|, and is provided with a pair of transversely-spaced apartbearing brackets 32 and 33 adjustably mounted and are parallel thereto.An elongated angle bar 4s extends between the'side rods 4I and 42adjacent the front end of the screen supporting frame, and a similarangle bar 50 extends between the rods 4i and 42 adjacent the rear endsthereof. 'Ehe angle bars 49 and '5G are adjustably secured to therespective rods 4I and 42 by clamping Vbrackets 5I, and are arranged tohave one of their angle portions horizontal and the other Vertical. Bymeans of the brackets 5I, the angle bars 4e and 50 may be adjustedlongitudinally in the direction of web travel along the rods 4I and 42to position the stencil frame supported thereby in the desired location.Y

The horizontal base portions 52 of the angle bars 49 and 5U extendtoward Yeach other and form'opposingY seats fora rectangular stencilscreen, which, in this instance, is made of four narrow wooden strips53, 54, 55, and 56, and secured together at their adjoining ends. Aprintingstencil sheet 51 is stretched across the bottom of the stencilscreen, said sheet 51 being preferably made of specially treated silkhaving the desired perforated design formed thereon through which thethin color paste may penetrate and Vbe applied by a vsc lueegee to theweb W (Figures 2 and 3). VAnangle piece 31 secured to the table topextension SI has a screw 38 threaded Ytherethrough into engagement witheach of the Y YbracketsBZ and 33V to permit them'to be held in anydesired position and to prevent said brackets from moving rearwardlywhen the machine is be- Stencil screen rods, 39 and [53,-and side bars4I and 42--the rear I endV rod 4e being pivoted in bearings 43 and 44carried bythe brackets 32 and 'A33 respectively; The rods 39, 4G, 4I,and 42 are connected together atv the cornersof the stencil frame byfour angle blocks 45, thus maintaining the frame Vinrectan- ',lFourvertically disposed posts 46 extend upwardly--one from each angle blockt-to support side Vrods orV trucks, 41 and 48 which are spaced above theside rods 4I and 42 respectively,

placed thereunder. In this instance, the front andrear strips 53 and 55of the stencil screen are removably seated on the horizontal portions 52Vof the angle bars 49 and 50 of the swingable stencil screen supportingframe.

rEhe stencil frame'comprising the strips 53, 54, 55, and 56, is seatedinY lthe carrying frame, comprising the bars 39,40, 4I, and 42, and maybe brought into exact register with the design on the stencil screen byadjustment of the vertical limit arm 58 (see Figures'2 and 3), of anadjustable guide bar having a horizontal Varm 59 which is secured to thetable top I 0 by bolts 60 and 6I which pass through elongated slots 62and 63 respectively, provided in the horizontal arm 59, and

which bolts are screw-threaded into the table top lil. The stencilframeris dennitely located at its front end by' a slidable block 64,adapted to be clamped adjustably to the angle-bar 49 by a thumb screw65, and an angle strip 66, secured to the stencil frame strip 53 byscrews 61, one arm 68 of said angle strip being adapted to engage theblock 64. Y

Lengthwise adjustment of the stencil frame is obtained by the use ofafpair of transversely spaced apart wood screws 69 and 10 (see Figures3, 4, and 8). The wood screws 69 and 10 are screw-threaded into thefront stencil frame strip 53 and have heads 1| which are spacedforwardly therefrom. Y

Y The screws 59 and 10 are each engaged by an invert-ed L17-shapedclamping block 12 (see Figure 8) having the rearleg 13 thereof providedwith a slet 14 extending upwardly fromV its lower edge and adapted toembrace the respective screw 69, 'l therein with the screw'head 1I. Athumb screw 15 is screw-threaded through the front leg l5 oi theU-shaped block 'i2 and engages a loose clamp plate 1'.' for engaging thevertical portion Vof the angle bar 49.110 securely clamp the frontstencil frame strip 53 thereto.v By manually rotating the screws 69 and'l0 by means of a suitable tool, such as ascrew driver, before clampingthem to the bai` 49, by the blocks 12, adjustment of the stencil framemay be made to compensate for anypossible warping thereof. The rearstrip 55 of the stencil frame may'be'detachably secured to the angle-bar 59 in any suitable manner, but sherein shown as being merely seatedtherein afreagarze (Figure 5) with its rear edge abutting the verticalportion 'i8 of said angle bar 50.

By means `of the above structure, it will be seen that the stencil frameis adjustable transversely and lengthwise upon its carrying frame andthat variations in width of different stencil frames may be compensatedfor-by adjustment of the vertical limit arm 58 and the adjustable blockBil.. Variations in the length of different stencil frames iscompensated for either by means of the adjustable angle bars i9 and 50,or the wood screws E9 and 10, or both.

The stencil screen, 53, 54, 55, and 56, may be manually-iiftcd from ltheunderlying web W Whenever it is desired to shift the'web, by swingingits carrying frame 39, 40, 4l, 42 upwardly about the hinged connectionof the rod 40 in the bearings d3 and lid as apivot.

Provision is also made of means to manually lift the stencil screencarrying frame, 39, d0, 0|, and d2, and such means comprises a pivotedfoot treadle Se which, as shown in Figure 2, is connected to the frontrod 39 yof the screen carrying frame through a system of links andlevers arranged with a mechanical disadvantage whereby a comparativelysmall movement of the treadle 8i) will move said frame a relativelylarge amount.

The foot treadle 50 is pivoted at 8| to a cross bar 82 extending betweenthe lower side bars 20, and provision is made Vof a short upstandinglink 83, which loosely connects the forward part of the treadle iil witha long vertical link 84. The upper end ofthe long link 8d is looselyConnected to a short vertical link 85, which in turn is pivoted to aninclined arm 80 at a point closely adjacent vthe lower xed end 8lthereof. The end S'iof the arm 8e is pivot-ed to the front intermediateupright 2i Vbetween a pair of angel blocks 81E-and 8G (see Figure '7)the right-hand part of the bracket, and the upper end 00 of the arm 86is connected by a chain, Si (see Figure 2), reeved over a pulley s2,supported on the rear surface of the upright 2i, said chain passingdownwardly from said pulley and being connected to a post 93 secured toa vertical slide 95, which is adapted to loosely embrace the upright 2I.

The slide 9d is connected to the lower end of an opstanding plate 95(Figures 2 and 3), which carries a short horizontal shaft 95 at itsupper end. The shaft 96 extends beyond the sides of the plate 95 and hasrollers 01 journaled on each end thereof. The rollers 91 engage blocks98 secured to the underside of the front screen frame rod 39 and serveto reduce friction. By' means of this construction, it will be seenthat, when the operator steps on the treadle 30, force will betransmitted through the links 83, 04, 85, arm 85, cha-in 9|, slide 94,plate 55, to the rollers SI, causing the front end of the Stencil screencarrying frame to swing upwardly and lift the stencil screen out Vofcontact with the web W. To assist the operator in this operation,lcounterweights 99 may be hung upon the arm 35 adjacent its upper end90. The stencil carrying frame is engaged-at its forward end by a pairof curved strips |54 and |55 (see Figures l and 8) which serve to guidethe angle blocks 45 as this frameis lowered into place.

The web W is adapted to be fed across the table top lil under thestencil screen 51 from oneside ofthe printing apparatus to the other. Inorder to avoid any stretching or movement of the web W,it is'temporarily secured-upon-a carrier band, or belt, |58, preferablyconstructed of heavy-ilexibleflpaper, by meansl of a non-dryingsticky`ad- 6 hesive which may vbevcomposed,.'for example,` of a mixture ofchina clay .and glycerine. /Bythe use of this adhesive, the carrier belt|00, may be repeatedly before replacement Vis necessary, due to the factthat it may be strippedtherefrom repeatedly without damage to the belt|00 or the web W. In most instances only the outer bres at theundersurface of the web W are impregnated by the adhesive.

revision is also made of a pair of spacer strips I0| Aand .|02disposedbeneathiboth margins of the carrier belt |00,` and preferablycemented thereto (see Figure 9). It `will be understood that said stripsI0! vand |02lmay, if desired, be riveted to the carrier belt |00 as byeyelets, within the scope of the invention. The combined `web W, carrierbelt |00, and spacer strips IOI and |02, are adapted to be guided acrossthe'table top I0, by means of a pair of transverse grooves |03 and itil,respectively, formed in the upper surface of said table top i0 (seeFigures 4, 5, and 6) When the web W `and the carrier strip |00 are woundinto a spiral coil upon a spool |05 (as shown in Figures l and 2), itwill be understood that-the belt Hit will. be spaced apart in successivelayers by the strips |0i and iBZ at its edges, thus providing an airspace therebetween, protecting the color paste printed on the web W andprevent* ing smudging of the table top I0 thereby. The color will thusbe permitted to penetrate uniformly. into the weband produce a sharp anddistinct reproduction ofthe design thereon. The edges of the web carrier`belt Illil outside the web are preferably coated with shellac or othersuitable material to seal them against moisture and afford additionalstifening.

The color paste employed in lthe screen printing apparatus is adapted tobeV forced through perforations inthe sten-cil screen 51 onto and intothe web W by means of a squeegee blade I 06 (Figures 2, 4, and 5),preferably made of Vsoft rubber and having its upperedge set .intoarecessed strip Id?. The strip |01 is hinged `as at |08 vto another stripIdil, located above it, whichstrip it@ is adapted to `be .clampedbetween a pair of transverse anglebars IIO andIII by a pair of thumbscrews H2.' The angle bars I I0 and |I are secured to the` forwardendsof a pairof short horizontal slide members H3 and IIA of invertedU-shape cross-section.. The legs of each inverted U-shaped memberstraddle the parallel side tracks il and lifandvthus guide the squeegeeblade H36 in its manual reciprocation bythe operator who grasps arelatively Ylongr handle `rod I I5 secured at one -end to the cross barsH0 and Ill, as shown in Figures 1 2, 3, 4, and 5. .It will be noted thatthe inverted `U-shaped guiding members IIS and lIli do notactually reston the racks 4l and 48, but the weight of this structure and thesqueegee blade |016 is irnposeddirectll7 upon the stencil screen El soas to Vcause the color paste to pass therethrough and uponthe webbeneath it. The pressure `of the squeegee blade |35 upon the screen maybe increased if desired by the use of suitable ring shaped weights I I-Esurrounding .a pair of vertical posts I'I extending upwardly from theguide members I I 4.

In operation, the-squeegee blade |06 willbe lifted at `each end of itsstroke and moved and lowered atctheoppositeside :of the mass of colorpaste so as to push it in the' reverse direction. This operation isreadily accomplished byrswing-l. ing the handle' rod H5 upwardly-andcausing .the rea-r ends l-IQL'and-fIZ of the-guide memberset I3 and ||4to engage the tracks 41 and 48 which act as fulcrums therefor.

t When the printing operation is completed, the squeegee blade It@ willbe raised away from the stencil screen l' and maintained in such raisedposition, whileV the stencil screen is also lifted and the web shiftedto bring a new unprinted portion into registry with the screen. For thispurpose, provision is made of a pair of transversely spaced apartstandards |2| and |22 (see Figure 3), secured to the table top H! at therear of the stencil screen supporting angle bar 5d (see Figures 3, 4, 5,Yand 5). Each of the standards |2| and |22 has a horizontal rearwardlyextending arm, |23, |24, and forwardly extending angle arm, |25, |25,respectively. The arms l'and i2 extend outwardly in opposite directionsand carry rollers |21, and the arms S25 and Ii extend inwardly toward,each other and carry rollers E28 (see Figures 2, 3, 4.-, and 5).

When it is desired to support the squeegee blade |56 up out of Contactwith the stencil screen 5l atthe'rear end of its stroke, it will merelybe necessary to tilt the handle VH5 upwardly to cause the rear ends I9and Its of the guide meinbers ||3 and H4 to be disposed under therollers I2?, and the rear cross bar iii to be disposed above the rollers|23 (as shown in Figure 5).

The web-carrying belt with the web IFJ adhering shaft |29 which extendsfrom its rear end, and has a sprocket |35 detachably secured to saidextendi ingtend by a set screw li. A chain, |32, is reeved over thesprocket, i353, and the sprocket, 2S on the hand Vwheel shafts 23,whereby rotation of the hand wheel fill on the take-up side of theapparatus will cause the web W to be fed across Ythe table top l5 fromthe feed spool.

In order to insure accurate printing, indicating Vlin-es |33 are markedat spaced intervals along the edge of the carrier belt lt, and a singleline |34 is marked on the table top i3. These .marks when in alignmentindicate to the operator that the web W has been properly positioned inacy As herein shown, a pair Vof identical spools |35,

are provided which may be selectively used for eeding and taking-up ofthe web. Each spool is permanently mounted upon a truck |35 V-havingcasters' |35 whereby it may be wheeied toward and away from theYapparatus torcarry the web into and vout of printing position.

In order to insure accurate registration of the printed designs on theweb, means'are herein provided on each side of the printing apparatusfor alining the spool carrying truck |35 with said apparatus. Thealining Vmeans above referred to includes two pairs of resilient arms|31, I 31a extending out- Y Vwardly from the corner upriglntsYV i2, I3,and II, `I4. The arms |37, |3`|d (see Figures 11, 15, and Y 16)-'areeach curved outwardly to facilitateV the movement of the side base bars|38 and |3l of the truck |35 into engagement therewith and toY guidethefeeding spool so that the web W to be printed will be in correcttranverse registry Vwith the stencil screen when it is fed into printingposition. f

In order to lock the spool truck I 35 in operating position provision ismade on each of said alining means of a toggle mechanism comprising alever |40 having one end pivoted as at I4I to the adjacent resilient arm|31, I3'Ia. A handle M2 at the other end of the lever Ifiil is providedto manipulate the same. Provision is also made of a thin rod |43 havinga hooked end |44 adapted to catch into an elongated slot |65 provided inthe side base bars |38 and |39 and pivotally secured to the lever |40intermediate its ends, said rod |43 passing through a vertical post |46which is arranged to rotate in the lever |40. A coiled spring |41surrounds the rod |43 and reacts between the post |46 and a washer heldon the outer end of the rod |43 by lock nuts |49 and |55. When it isdesired to hold the truck in the locked position (as shown in Figure 14)the hooked end |44 of the rod |43 will be connected to the truck sid-ebars |38 and |39 by engagement in the slot H35 nearest 'thereto and thelevers |115 will be swung from the position shown in Figure 16 into thetruck-locking position as shown in Figure 14. If desired, an additionalslot |45 may be used so that the trucks may be readily reversed andeither side thereof selectively applied to the printing apparatus.

Web drying apparatus While the apparatus is being operated, and afreshly printed web W is being wound continually upon the take-up spoolH55, a constant flow of dry air will be directed against the surface ofthe web on said spool by mean of a duct |5| leading from a central motordriven air blower |52 (see Figure 1). Additional drying may also beobtained by: means of an auxiliary blower, not shown, to force dry airinto the hollow spool shaft |29, which air will be caused to flowoutwardly through Vperforations |53 therein and between the layers ofthe spiral coil of web W wound thereon.

In'the modified form of web-.drying means illustrated in Figure 10, acontinuous row of spacedapart teeth ISG are provided on the underside ofthe spacer strips |6| and 52, which strips are similar in other respectsto the plain spacer strips ISI and |52, shown in Figure 9. In Figure theteeth consist of spaced-apart eyelets |63 attached to the spacer beltsand have openings Y I 54 therebetween.

It will be seen from these modified forms of spacer belts, shown inFiguresl() and 11, that a stream of dry air under pressure may besupplied to a special form of spool'i having a hollow shaft |66 which isplugged adjacent one of its end anges |51, as shown in Figure 13. Thehollow shaft |36 outside of the flange I5?, is provided withperforations or slots |58, to permit the dry air stream to passoutwardly into a hollow Vend casing I'Ii which is suitably secured inspaced relation at its outer'edge to the flange |61 to forni an enclosedchamber. The flange IS? is also provided with a series of arcuate slotsin alignment with the openings |54 between the teeth I or eyelets |63 onthe spacer-strips and |62, whereby the stream of air Vblown into thecasing will be forced in a longitudinal direction through the successivelayers of the web W spirally wound on the spool |65.V

OperationV The operation Vof Ythe above described screen printingapparatus is substantially in accordance with that Ydisclosed in theabove-mentioned Patent No. 2,210,474. In brief, the operation is asfollows:

Assuming the Ysq'ueegee blade |86 is held in raised position by therollers |21 and |28 (see Figure 5), the stencil screen frame will beswung upwardly by depressing the treadle 80. The webcarrying belt Willthen be drawn across the table top l0 from the feeding spool |05 withthe spacer strips |0| and |02 guided by the grooves |03 and |84,respectively. The free end of the web-carrying belt |09 will then beattached to a take-up spool |95, which has rst been locked in place atthe other side of the printing apparatus, by threading it through theslot |12 in a longitudinal bar |13 of the take-up spool, as indicated inFigure 12. The hand wheels 21 will then be turned to bring the iirstmark |33' on the carrier belt into alignment with the mark |34 on thetable top l0 whereupon the stencil screen holding frame will be loweredto cause said screen to engage the web W. The squeegee blade |06 willthen be lowered upon the rear end of the stencil screen 51, and theproper quantity of color paste will be then placed upon the screen 51 infront of the blade |06, which may then be pulled forwardly by means ofthe handle ||5.

When the squeegee blade |95 is in its forward position after havingtraversed the length of the screen 51, it will be lifted by tilting thehandle I upwardly and placed in front of the mass of color paste, andthen pushed rearwardly to spread the same along the screen 51. After thedesired number of strokes of the squeegee blade |06 have been made, saidblade will be latched in its raised position as above described. Thestencil carrying frame will be swung upwardly by means of the treadle80. The web W will then be fed along the desired amount to bring thenext desired indicating mark |33 on the web-carrying belt into registrywith the mark |34 on the table top I0. This procedure will be continueduntil the web has been completely unrolled from the feed spool, andwound up on the take-up spool.

After the spool of unstenciled web has beenunwound from the feedingspool, printed, and wound up on the take-up spool, the truck carryingthe latter may be unlocked and rolled away from the printing apparatusfor drying or other treatment. It will then be returned to the printingapparatus on either side thereof if desired, and the previous take-uproll will then serve as the feed roll-it being merely necessary to shiftthe crank handle 30 to the other shaft 23 to operate the feedingmechanism and take-up mechanism, as described above.

While there have been disclosed in this specilication several forms inwhich the invention may be embodied, it is to be understod that theseforms are shown for the purpose of illustration only, and that theinvention is not to be limited to the specific disclosures, but may bemodified and embodied in various other forms Without departing from itsspirit. In short, the invention includes all the modifications andembodiments coming within the scope of the following claims.
